IMPROVEMENT iN GAS-REGULATORS.

Specification forming part of Letters Patent No. 142,155, dated August26, 1873 application filed May 17,1873.

To all whom it may concern.-

Be it known that I, CHARLES H. ED- WARDS, of Chicago, in the county ofCook and State of Illinois, have invented a new and useful and ImprovedGas-Regulator; of which the following is a full, clear, and exactdescription, which will enable others skilled in the art to which myinvention appertains to make and use the same, reference being had tothe accompanying drawing forming a part of this specification, and inwhich- Figure 1 is an elevation of my improved regulator; Fig. 2, avertical central section thereof; and Fig. 3, a top or plan view of thelower part of the bulb.

The object of my invention is to cause a more even flow of gas at theburner; and to that end my invention consists in arranging in thesupply-pipe, between the meter and the burner-preferably near themeter--a porous diaphragm and a weighted valve, operating in connectionwith each other, and constructed and arranged together substantially ashereinafter described. It also consists of the regulator device as awhole, as a new article of manufacture.

In the drawing, A represents a spherical bulb, made in two separateparts, A and A, united to each other by means of a screw attachment, andprovided with screw-threaded tubular projections, by means of which itmay be readily applied to the supply-pipe. B is a suitable packing,arranged between the parts A and A. C is an annular shoulder or flangeprojecting inwardly from the part A. D D are diaphragms of finewirecloth. E E are thin layers of cotton or cotton batting, or otherequivalent material, arranged between the diaphragms D D; and F is adiaphragm of haircloth, arranged between the layers E E. The diaphragmsD D and F, and the layers E E, are of such diameter as to be supportedon the flange or shoulder C.

The diaphragm F is not essential; but I deem it preferable to employ it,for the reason that it increases the firmness of the whole diaphragmwithout destroying its porous and yielding or flexible features.

Any or all of the diaphragms D D and F may be made either of hair-clothor of wirecloth.

G is a valve, somewhat less in diameter than the diameter of the openingsurrounded by the flange or shoulder C.

I deem it preferable, but not essential, to make the valve Grdish-shaped, and to arrange its concave face downward, as shown.

gis a stem or pin attached to the central part of the valve G, andpassing through the center of each of the diaphragms D D and F. g is aweight attached to the lower end of th stem g.

When the device is made large, and there is danger that the weight ywill draw the di- -aphragms from their seat, the flange C may heprovided with radial supporting arms, as represented in Fig. 3.

It will be observed, from the foregoing description, that an irregularpressure of gas at the meter will not act immediately on the flame, forthe reason that an uneven pressure will be resisted, to a great degree,by the passage of the gas through the regulating device, and that aflickering light will be thus prevented.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. The combination and arrangement, in a 'gas regulator, of thediaphragms D, layer E,

and weighted valve G, all substantially as and for the purposesspecified.

2. The combination and arrangement, in a gasregulator, of the diaphragmsD D and F, layers E E, and weighted valve Gr, all substantially as andfor the purposes specified.

3. As a new article of manufacture, a gasregulator consisting of theparts A and A, diaphragms D, layer E, and weighted valve G, allconstructed and arranged together substantially as shown and described,and for the purposes set forth.
